The untapped potential of the GENSAT mice—A valuable resource for developmental biology

Summary
Gene Expression Nervous System Atlas (GENSAT) transgenic mice express EGFP, tdTomato, or Cre recombinase in a wide range of cell types. The mice and the bacterial artificial chromosome transgenes are available from repositories (MMRRC or CHORI), thereby making these resources readily available to the research community. This resource of 1,386 transgenic lines was developed and validated for neuroscience research. However, GENSAT mice have many potential applications in other contexts including studies of development outside of the CNS. The cell type‐specific expression of fluorescent proteins in these mice has been used to identify cells in living embryos, in living embryo explants, and in stem or progenitor cell populations in postnatal tissues. The large number of fluorescent protein driver lines generated by GENSAT greatly expands the range of cell type markers that can be used for live cell sorting. In addition, the GENSAT project has generated 278 new Cre driver lines. This review provides an overview of the GENSAT lines and information for identifying lines that may be useful for a particular application. I also provide a review of the few published cases in which GENSAT mice have been used for studies of embryonic development or analysis of stem/progenitor cells in nonneural tissues. genesis, 2016. © 2016 Wiley Periodicals, Inc.
